After doing a "sudo chkrootkit" everything looked fine except this statement:
Searching for suspicious files and directories
/lib/modules/2.6.12-9-386/volatile/.mounted
Should I be worried about this readout?

It's my experience that chkrootkit is sensitive to false positives. I too got
Searching for suspicious files and dirs, it may take a while...
/lib/modules/2.6.12-9-k7/volatile/.mounted
It looks like some kind of lock file, zero length, was created at the same time as my computer was last booted, 2.6.12-9-k7=$(uname -r). Of course, if you'd suspect this file, you should not use the binaries / tools on the same machine to check it. However, I'm not worried, I think it's false positive.

I got the same thing out of chkrootkit, but my snort alert log looks like
the below. 192.168.0.106 is my IP address. I looked at the other IP addresses,
the first few go to Yahoo and AOL, and the last few go to xlogicgroup, which
I would have no idea why I would be contacting that site.
This is a fresh install, after my debian showed similar things in the snort
log.
I will try again w/o starting up GAIM.

However, I'm not worried, I think it's false positive.I agree, the same thing happens when you run chkrootkit on Gentoo, there are lots of 0-length ".keep" files to stop the package manager from deleting certain directories, and these are all flagged as suspicious too.
